Don't think that if your heart rate falls below 60 that something is wrong. It is not uncommon while at rest, to have your HR dip below 60. Some people have rates that drop into the 30'3&40's while sleeping. Our heart rates will fluctuate which, for most, is a normal variable.on't think that if your heart rate falls below 60 that something is wrong.

GPS Receivers. Any navigation solution provided by a GNSS Receiver is based on the computation of its distance to a set of satellites, by means of extracting the propagation time of the incoming signals traveling through space at the speed of light, according to the satellite and receiver local clocks.
The receiverâs functional blocks that perform these tasks are the antenna, the front-end and the baseband signal processing (in charge of acquiring and tracking the signal). Once the signal is acquired and tracked, the receiver application decodes the navigation message and estimates the user position.
